I can't vote this one very highly since it doesn't look like it has much potential or hook in and of itself, but I like the visual style. That said, the controls feel unresponsive, which is really bad in this genre. I couldn't tell how to convince the knight to go precisely where I wanted. If you continue work on this or re-use the code, I would suggest fixing the feel of the movement early, perhaps by tweaking the knight's inertia.
